Application filed Decemher 8,1913. Serial No. 805,245.

To all whom it may concern:

Be it known that 1, CHARLES S. BURTON, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented new and useful Improvements in Driving-Gears, of which.

of a motorcycle wheel equipped with a gear which is the subject of this invention. Fig.

2 is a front view of a portion of the gear- Fig. 3 is a rear view of a portion of the gear. Fig. 4 is a section taken as indicated at line 44 on Fig. 2.

The gear which is to be described consists of a metal ring which is split into two portions, 1 and 2, by sawing it through at i 3, or preferably, by sawing it partway through and then breaking it so that the roughened edges will fit snugly into one another, and will keep the space between the teeth where the cut is made the same as the space between the other teeth of the gear. A splicing plate, 4, provides the means by which the two portions, 1 and 2, of the gear are joined together. This plate, 4, has projecting from it four bosses, 5. which fit firmly into corresponding holes, 5, drilled through the ring, two on either side of the sawcut, 3. These bosses, 5, may be conveniently formed by punching the metal of the plate, 4, partway through, as shown in Fig. 4. For holding the plate, 4, against the face of the gear so that the bosses, 5, may serve to couple the two portions of the ring securely there is provided a clamping bolt, 6, which screws into a threaded aperture, 4*, in the splicing plate. The shank of the bolt, 6, is accommodated in an aperture, 3 formed in the gear at the line of the sawcut, 3.

This construction permits the gear to be very easily separated for encircling the axle of the wheel to which it is to be fixed, and very readily assembled by the insertion of the two clamping bolts, 6, 6. For securing a splicing plate adapted for connecting'said the gear to the spokes of the wheel any well known fastening means may be used, being arranged as indicated at 7,0n'Fig. 1.

I claim r 1 1. A gear comprising separable sections,'

sections and having a plurality of lugs projecting from one face, the gear sections having apertures positioned to receive said lugs. at least two of which are disposed at one side of the line of. separation of the sections, and means for holding the plate againstthe gear sections with its lugs engaged in said apertures.

2. A gear comprising separable sections, a splicing plate adapted for connecting said sections and having a plurality of lugs projecting from one face, the gear sections having apertures positioned to receive saidlugs at least two of which are disposed at one side of the line of separation of the sections, and a clamping bolt for holding said plate against the gear sections, said sections having an aperture to accommodate said bolt at their line of separation with a portion of said aperture extending into each section.

3. A gear, comprising separable sections, a splicing plate adapted for connecting said sections and having a plurality of lugs proj ecting from one face, the gear. sections having apertures positioned to receive said lugs side of the line of separation of the sections, and a bolt for holding the plate against the gear sections, with said lugs engaged in said apertures, said plate being threaded to re-. ceive the bolt.

4. A gear comprising separable sections, a splicing plate, adapted for connecting said sections and having a plurality of lugs projecting from one face, the gear sections hav-' ing apertures positioned to receive said lugs t at least two of which are disposed at one a side of the line of separation of the sec- I tions, and a clamping bolt for holding said plate against the gear sections, an aperture being'formed through the gear to accommo date said bolt disposed to extend into the plane of separation ofthe gear sections. 5. A gear comprising separable sections, a splicing plate adapted for connecting said sections and having a plurality of lugs struck out from one face of the plate and integral therewith, the gear sections having aaertui'es )ositioned to receive said 111 s at Chica o Illinois this 2nd da of December,

b b 7 3 y least two of which are disposed at one side 1913.

of the line of separation of the sections, and h T a means for holding the plate against the CHAHLLS BJRTQLT' gear sections With its lugs engaged in said Witnesses: apertures. RoBT. N. BURTON,

In testimony whereof Witness my hand at EDNA M. MAGINTOsH.
